I have a similar problem with HP DL380 servers with a RAID controller that uses the "cciss" driver. Disks show up under /dev/cciss like:
/dev/cciss/c0d0p6 on / type ext3 (rw,errors=remount-ro) And since grub no longer understands that, grub-mkdevicemap leaves me with an empty device.map and I get grub-probe: error: Cannot find a GRUB drive for /dev/cciss/c0d0p6. Check your device.map. from update-grub. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
